| Outline of Final Research Achievements |
This study aims to develop the desiccant dehumidification and heating process for agricultural greenhouse. At first, influences of some operating parameters on the adsorption outlet air temperature and humidity were studied. It was found that there were optimum values of the rotation speed and adsorption/regeneration flow ratio at which the temperature in the process outlet air became the largest. Influence of regeneration air temperature on the temperature increase and the amount of adsorption was quite serious since the difference of relative humidity between adsorption and regeneration air became small as the regeneration temperature decreased. Also, the cooled rotor during regeneration step absorbed heat of adsorption which is generated at the beginning of the adsorption zone. Excluding of the low temperature air leaving the beginning of the adsorption zone is useful to obtain higher temperature process outlet air even when the regeneration air temperature is low.
